A bunch of flowers is a lovely gift and will look beautiful in your home. However, they will also have a limited lifespan once they have been cut, so you need to look after them as well as possible in order to make them last as long as possible. In general, you can perhaps expect a bouquet to last for around 2 weeks, though this also largely depends on the types of flowers used. A spring bouquet, for example, will not last as long as other forms of flowers as they use fresh, delicate blooms. Flowers like roses and tulips might look their best for up to a week, and other flowers like freesias may last for longer.
If you are going to have a bunch of flowers for as long as possible, you can also help by looking after them. Change the water regularly so it doesn’t become cloudy, and use plant food to help your flowers thrive.
